The AI-AB Switcher is the size of a deck of cards with 12volt power and ground.

What It Does:

Audio is heard through one of our Audio Interrupt products or through an External Speaker when connected to the passive Non-Priority audio source when active. User's choice as to which device is Priority.

When audio becomes active on the Priority, input audio automatically switches from Non-Priority to Priority source to be heard.

Three seconds after the last voice message has been received, it automatically returns back to Non-Priority input.

Built to last, a water proof potting compound is used on this product to encapsulate the circuitry and cable assembly that protects against temperature change, vibration, dust or accidental immersion in water.
